Dynamic Output Feedback Finite-Horizon Control for Markov Jump Systems With Actuator Saturations

open access: yesIEEE Access, 2019
This paper considers the problem of asynchronous observer-based finite-horizon control of Markov jump systems (MJSs) with actuator saturations. The hidden Markov model is employed to describe asynchronous phenomenon between observer-based controller and ...

On the Equivalence Between Canonical Forms of Recursive Systematic Convolutional Transducers Based on Single Shift Registers

open access: yesIEEE Access, 2014
Standardized turbo codes (TCs) use recursive systematic convolutional transducers of rate b/(b + d), having a single feedback polynomial (b+dRSCT). In this paper, we investigate the realizability of the b+dRSCT set through two single shift register ...

A Soft Robotic Cover with Dual Thermal Display and Sensing Capabilities [PDF]

open access: yes, 2020
We propose a new robotic cover prototype that achieves thermal display while also being soft. We focus on the thermal cue because previous human studies have identified it as part of the touch pleasantness.
